Masscomps were 68k based machines, they had a whole bunch of stuff for
real-time and data-acquistion type stuff.  They ran something called
RTU -- real-time Unix -- which was a weirdo sysv / BSD hybrid, not fun
to use.  If the 5400 is the machine I remember it's a 68020 machine
but it may have a lot of cards for other stuff in.  If it *is* the
machine we had it was deeply unreliable.  Masscomp got bought by
someone else later on but I forget who, so they sometimes get badged
as some other make.

I would run away, fast.
